National Find a Rainbow Day is a special day serves as a reminder for individuals to seek out a glimmer of hope in the heavens above. Rainbows, with their enchanting allure, are a captivating meteorological occurrence that many find awe-inspiring. This occasion presents a chance to delve into and admire the splendor of nature. day to honor rainbows: ROYGBIV to help them to remember the sequence of colors in a rainbow: red, orange, yellow, green, blue, indigo, violet. Many forms of airborne water can cause a rainbow including, rain, mist, spray, and dew.

Prism Makes a Rainbow:
Infrared Explained: The Visible Light Magic Window sees the same part of the spectrum as our eyes see. Visible waves are a little shorter than the size of a bacterium. By the way, in the visible light range of the electromagnetic spectrum are the separate smaller ranges that our eyes see as different colors. A prism separates white light into its different wavelengths. White light goes in, all the colors of the rainbow come out. In the visible range, red has the longest wavelength, while violet has the shortest.

Viewed: When white light passes through a prism, it is divided into its various colors. A prism is a crystal with a specific shape. If you were to explore The Land of the Magic Windows, you would discover that the light visible to us is just a small portion of the different types of light energy present in the universe – including the light surrounding you! Similar to energy moving through the ocean, light energy also moves in waves. Some light moves in short, rapid waves, while others move in long, slow waves. The waves of blue light are shorter compared to those of red light. Each color of light has its own unique wavelength. Light always travels in a straight line unless it encounters an obstacle that causes it to either reflect (like a mirror), refract (like a prism), or scatter (like the molecules in the atmosphere). When sunlight enters Earth’s atmosphere, it is scattered in all directions by the gases and particles present in the air. Blue light, in particular, is scattered in various directions by the small air molecules in Earth’s atmosphere. Blue light scatters more than other colors because it consists of shorter, smaller waves. This phenomenon explains why we typically see a blue sky.

Photo #1 taken with a Samsung Galaxy S24 with the factory triple camera system: 50 MP sensor with an f/1.8 aperture and OIS, ultrawide camera has a 12 MP sensor with an f/2.2 aperture and a 120-degree FOV, telephoto camera has a 10 MP sensor with an f/2.4 aperture and 3x optical zoom.

Infrared Explained: Any visible light frequencies are reflected and refracted into any rainbow’s arc and show up as individual colors starting at the violet range all the way to red. The red spectrum is the longest ray, almost a wave as the longer spectrums have the personality of waves. Any infrared light is also being reflected and refracted but it is NOT visible to the eye. Since infrared light is subject to being absorbed as heat, the light does not show up as a lighter portion of the infrared film, rendering the infrared band appearing to be darker than the non-infrared sectors of light. Also notice “ghosting” of leaves on some of the trees. Since is is a darker value, it is showing of the branches transpiring water, therefore being cooler (the process is what gives that “cool” feel of being by plants). This was the original great asset of infrared photography’s use for military purposes in the jungles.

Photo #2 is an image overlay of the visible light photo on top of the infrared. I allowed the transparency to see both photos equally. See the below two photos for exposure information for each of the two photos..

Infrared vs. Visible Light Rainbow: Photo 2 & 3 are photos are of a rainbow in Oak Forest, Illinois, of a repeat post of the absolute original “Photo Of The Day” (now “Featured Photo”) segment that started Labor Day weekend in 2019. In the segment, I show the difference between a rainbow in an infrared photo by displaying the spectrum they use as compared to a visible light photo. Note that the spectrum is down on the near side shifted over and out of the red spectrum, as the featured rainbows show the results.
